Authorizes State, county, and municipal law enforcement officers to access certain crime scenes and evidence.

This bill authorizes all New Jersey state, county, and municipal law enforcement officers to access crime scenes and evidence under their agency's jurisdiction. It directly affects officers (who gain clear access rights) and anyone who obstructs them (including federal officers), making such obstruction a violation punishable under existing law. The key provision requires officers to access evidence only within their agency's responsibility, while prohibiting interference with this access. The Attorney General must issue implementation guidelines, and the law takes effect four months after enactment.
